Quick Print in PdfViewer

[k]

Do we have support for quick print in pdfviewer. Also can you provide a sample project using 2012 q1 Radpdfviewer as i am having issues to implement it.

It gives me KeynotFound error

Hi,

We will check if there is an issue when the PdfViewer is used in an application run on Windows XP.

1. Silverlight does not support silent printing. The print dialog should be user initiated or the application will throw a SecurityException. More info about the printing in Silverlight you can find here.
2. Please find attached a project that is mostly the same as our online demo. You should be able to run it when you fix the references to the latest 2012.1.215 release (if needed).

Kind regards,

Hi,


I will soon be looking into this component. It looks very nice.


I do have a question regarding the pdfViewer and it looks similair to this one:


- Is it possible to silent print a document? We are running the application out of browser and in full trust.


Thanks in advance!


Sincerely,

Edward

Hi Edward,

Currently, it is not possible to print without the PrintDialog. However, we have scheduled such a feature in the WPF version of RadPdfViewer for the Q2 release. When we start implementing it, we will do a research to see if it is possible to print silently in SL 5 OOB application. If so, we will try to implement it in this use-case as well.

Great.  

Just for extra info: I can print silently via SL5 in full trust but only ascii.  It is only pdf (and doc etc. ) what is not working for me.

To give you  a clue how I did it :)



this code is used for windows applications:

and change for silverlight the managed to unmanged like this

  public static bool SendManagedByteArrayToPrinter(string pPrinterName, byte[] pPrintByteArrayManaged, string pDocumentTitle)
        {
            bool result;
           
            var unmanagedHandle = GCHandle.Alloc(pPrintByteArrayManaged, GCHandleType.Pinned);

            try
            {

// !! must be translated to utf-8 first??

                var ptrUnmanaged = unmanagedHandle.AddrOfPinnedObject();
                result = SendBytesToPrinter(pPrinterName, ptrUnmanaged, pPrintByteArrayManaged.Length, pDocumentTitle);
            }
            finally
            {
                unmanagedHandle.Free();
            }


            return result;
        }

Hi Edward,

Thank you for the follow-up and the valuable insight. We will have this in mind when we start to implement the feature.

Hi,

Is there already any progress on the matter ?

Thanks in advance.

Hello Edward,

We have scheduled this feature for the SP that will be released at the end of the month. If everything goes according to plan, it should be ready by then.

Hello Reinhard,
Here is a sample code demonstrating how to print silently in Silverlight:

this.viewer.Print(new Telerik.Windows.Documents.Fixed.Print.PrintSettings("Document1", true));

All the best,

Thanks. I will give it a try.

Excuse me,
this will print OS native or via SL conversion?

Hi Paolo,

RadPdfViewer uses Silverlight printing.
